Abstract: The pressure regulator has a closing element which is designed as a sealing body (51) for a double-seat valve (34, 46, 50) and has a tubular extension (52). The aim is to ensure that the sealing body (51) does not give rise to friction and wear on the control rod. The intention is to eliminate a danger area in the pressure regulator. In addition, the double-seat valve (34, 46, 50) is to be of very simple construction. This is achieved by virtue of the fact that the tubular extension (52) of the sealing body (51) is secured in a definite position on a sleeve (36) containing a duct and the lift of an outlet valve (48) of the double-seat valve (34, 46, 50) is provided by a certain axial flexibility of the tubular extension (52). <IMAGE>
Patent SE-7708923-L (SE)
IPC: F24D7/00
Filed: 1977-08-05
Abstract: Energy is stored by heating a salt to a temperature above its latent heat of fusion to convert the salt to a liquid state. Heat is retrieved by moving a heat transfer fluid that is immiscible with the salt and has a density less than that of the salt over the top surface of the liquid salt at such a velocity that the upper layer of the salt is emulsified with the heat transfer fluid to crystalize the salt in the upper layer. Heat is thereby exothermally surrendered to the heat transfer fluid and the crystalized salt gravitates from said top surface, thereby maintaining the top surface in a liquid state. It is preferred to move the heat transfer fluid over the top surface of the salt in either a vortex pattern, or an outward radial pattern.

Abstract: A heat pump installation for heating a building, wherein the ground is used as a heat source, as a heat exchanger for extracting heat from the ground comprising a series of heat on exchange ducts 6 radiating from a chamber 2 in the ground. Each duct 6 comprises an outer pipe 8 and an inner concentric pipe 10. The pipes 8 are connected to an inlet header 12 for the heat exchange fluid and the pipes 10, which are lagged, are connected to an outlet header 14 for the fluid. The pipes 8 are introduced into the ground by a ram borer which is much more economic than the usual technique in which a pipe network is introduced into a large excavation and the excavation is then backfilled. Also the duct can penetrate much deeper into the ground than was previously practicable and thus more heat can be extracted from a smaller area of ground. <IMAGE>

Abstract: The invention relates to a vibrator for compacting soil. The object of the invention is to provide a vibrator having an improved manoeuvrability. The vibrator comprises a bottom plate (8) and a vibratory element (10) supported thereby. The vibratory element comprises two in synchronized opposite directions rotatable shafts (62, 64) driven by hydraulic motors and each supporting an excentric weight (66, 68). The relative position of the excentric weights is adjustable in order to impart to the vibratory element a vibratory motion which has the desired direction. The vibratory element (10) comprises two hydraulic motors (12, 14) connected with each of the shafts which are connected with each other by means of a device (70, 72) for transmitting the rotational motion of the one shaft to the other shaft. At least one portion of the motion transmission device connected with the one of the shafts is rotatable in relation to the shaft between two engagement positions which are positioned at an angle distance from each other. The vibrator comprises a control device (30) for supplying a main flow of hydraulic fluid to either the one or the other hydraulic motor (12, 14). On each occasion the shafts are driven by the one or the other hydraulic motor, one of the shafts being thereby driven directly and the other shaft being driven indirectly through the motion transmission device. Thereby the portion of the motion transmission device rotatable in relation to its shaft takes different engagement positions dependent on whether the portion connected with the shaft is driven directly by the hydraulic motor connected with said shaft or indirectly by the hydraulic motor connected with the other shaft.

Abstract: A portable electric stapler wherein a bladelike impeller is reciprocable by the armature of an electromagnet which is energizable a selected number of times so that a staple which is introduced into a housing channel in front of the impeller is gradually driven into a workpiece. The magazine for staples and that part of the housing which defines the channel are movable relative to the impeller between a first position in which a pusher can expel a staple from the magazine into the channel and a second position whereby the impeller separates the foremost staple from the stack of coherent staples in the magazine. The impeller blocks the outlet of the magazine during the intervals between successive energizations of the electromagnet to thus prevent entry of a fresh staple into the channel before the driving of the preceding staple into the workpiece is completed. The rearward movements of the armature and the impeller are braked by a pneumatic brake or by a shock absorber. The electronic control circuit of the stapler can be adjusted to select the number of successive energizations of the electromagnet.

Abstract: A cylinder for a printing press in which the gap for receiving the ends of a plate or blanket is skewed at an angle with respect to an axial length on the surface of such cylinder such that streaking of the printed product as is visible to the human eye is essentially eliminated. Such improved cylinders have a linear skew width greater than the linear gap width with the trailing end of the trailing edge of the gap being located opposite a non-gap area of the other of such cylinders cooperable therewith when such gaps are in their full overlying position. Such improved cylinders have a non-rotative relative motion when the gaps cross over each other such that the cylinders gradually enter into a zone of decreased pressure therebetween and gradually exit from such zone whereby axial deflection of the cylinders is minimized. Such improved cylinder is particularly suited for a blanket cylinder, a pair of blanket cylinders or plate cylinders or the well known combinations of blanket and plate cylinders. Further, since the gaps are skewed, a plate or blanket in the form of a parallelogram is provided to improve the mounting of such a plate or blanket to a cylinder having a skewed gap of this invention.

Abstract: In a method and a device for anchoring timber framing (3, 4) movably to a substructure, e.g. in supplementary insulation of roofs or walls, timbers are laid out to cross over each other on the substructure in its entirety. Holes (7 or 8) are then made in the substructure at each crossing of the timbers as fastening devices (2, 10 or 20, 10) are anchored in the substructure. The holes may be through holes or they may bottom in the substructure, and they have an area which is greater than the arm (9 or 20) associated with the fastening device and which is to be inserted in the hole. Clamping is done by the holding means of the fastening device being engaged with the substructure and the bracket (10) of the fastening device gripping round the framing and urging it towards the substructure. The holes are then filled, suitably with a porous moisture-sealing material. The anchorage of the timber framing will be movable so that sheeting with larger surface than up to now can be erected without risk of damage or other undesirable effects.
